The purpose of this work is to develop a 350 x 600 element X-Y addressed electrophoretic image display EPID. The design and fabrication of a control-grid electrode supported by a Mylar dielectric has been investigated. Computer modeling is being used as a design aid, and ion-beam milling has been successfully used to fabricate the Mylar control-grid electrode. The Mylar dielectric is attached to the In2O3 coated substrate using heat and pressure alone or in combination with an epoxy adhesion promoter. Good seals, with occasional nonbonded areas, were obtained by heating the Mylar while applying pressure. Better seals were obtained when one side of the Mylar was coated with epoxy. Operating life-test results indicate no adverse interactions between the electrophoretic suspension and the Mylarepoxy seal. Computer modeling of the electrostatic potential in the device is in progress.
